NAME

Haver::Reload - Reload modules if needed

SYNOPSIS

  use Haver::Reload;
  Haver::Reload->init;

  # Now, reload things:
  my @did = Haver::Reload->reload;

  # @did is a list of modules we reloaded.
 
  # change the default module matching pattern:
  Haver::Reload->pattern(qr/^MyMod::/);

  # Try to load a module at run-time:
  if (Haver::Reload->load('Haver::Server::Monkey')) {
    print "OK!\n";
  } else {
    print "Can't load Haver::Server::Monkey!\n";
  }
  # Note, the above is probably always going to be used as a way
  # to force-reload something.
  
  

DESCRIPTION

This module reloads modules, if the module is reloadable and has changed since init() was last called. The module must also match $Haver::Reload::Pattern, which is a regexp thingy, made with qr//. A module is considered reloadable if it contains a package global scalar $RELOAD and if that said global is true.

$Haver::Reload::Pattern defaults to qr/^Haver::/.

EXPORTS

Nothing at all.
